If I use jQuery AJAX to call a specific ASP.NET page method how to have that method return a value back to the AJAX method that called it?
Update
My situation is I have an existing web application with many existing methods. I would like to be able to use jQuery to execute some of these methods and then update the UI with the results. My mandate is to stay away from ASP.NET AJAX and stick with jQuery. Management is concerned about continued development and support with ASP.NET AJAX from Microsoft. I agree with them.
You can use JQuery with page methods this way: http://encosia.com/2008/05/29/using-jquery-to-directly-call-aspnet-ajax-page-methods/
The success callback contains a parameter with the returning data.
HTH.
